Attempt to Unlock, TWRP fails - ZTE Axon 7 Questions & Answers

Hi Guys,
I purchased new Axon 7 A2017U in February updated to Nougat 7.0 (auto update on the air). I have read and followed every guide on this forum to unlock, install TWRP and eventually root my phone, but all attempts failed. I did enabled "unlock oem" in Dev. Options and installed the Qualcomm driver as instructed. After rebooting to edl, my phone is recognized on com 3 in Device Manager (using Windows 10 64bit). However, "axon7tool -r gpt . . . . . " does not connect to the phone. I used MiFlash program and flashed "fastboot-Unlock", flash succeeds but the step after that failed!!! I must have spent no less that 10 hours researching and trying every guide, but all failed. I would sincerely appreciate it if one of our experts could direct me to an up-to-date clear guide or write an up-to-date guide to successfully accomplish this goal because none of the existing guides worked for me. By the way, I tried all the "One Click Root" apps (King Root, KingoRoot, iRoot, Vroot, MobileGo, etc.), they all failed.
Thank you in advance.

Would like to help but I have no idea what you are doing. If you want to use miflash method (latest) then what is the issue? You flashed unlock package, then you should be able to boot into fastboot and unlock.

Ok i'll try to direct you step by step.
1. Download the files from the edl guide and extract them.
a. B15 full nougat
b. B15 twrp
c. Minimal adb fastboot files
d. Supersu 2.79 (not the SR3 one)
2. Reboot to edl.
3. Miflash b15 full nougat. Do not reboot yet.
4. Miflash b15 twrp. Reboot to bootloader.
5. Open folder you extracted the minimal adb, hold shift then right click, open command window.
6. Type: "fastboot oem unlock" then confirm on the phone.
7. Reboot to twrp then keep system read only.
8. Flash supersu 2.79.
9. Go to twrp terminal, type: reboot disemmcwp
10. Wait for system bootup and go thru the setup.
Hope this helps.

In miflash it doesn't matter..

Thank you indeed, I succeeded in unlocking my Axon 7. I noticed that when I reboot the phone, there is a message indicating that the phone is unlocked and asking to lock it; it gives 5 seconds and then it boots. Is this expected?

[Root] Zenfone 2 Official Android 6.0 Root + Xposed and Downgrade

**WARNING** You need to have background knowledge of adb, fastboot, twrp, sideload.. before you can go on with this thread.
1. All credits go to @shakalaca. If you like his work, please make him a small donation for encouragement.
2. This is a systemless root. Yet you need to unlook Lollipop before upgrading to Marshmallow.
3. Flashing the attached SuperSU file modifies stock boot.img. In case you receive an OTA file later, do
**REMEMBER to FLASH BACK TO STOCK Android 6.0 BOOT.IMG** to unroot before upgrading to official Android 6.0.
Root:
1. Unlock your device in Lollipop, then upgrade to Android 6.0
2. Once you are in Android 6.0, fire the following command to boot twrp. <twrp.img> is the twrp recovery file. This TWRP is recommended.
HTML:
adb reboot-bootloader
fastboot boot <twrp.img>
3. adb sideload the attached SuperSu file in twrp. /OR install the SuperSU in twrp if you saved it in device storage.
4. reboot system. You will see a warning screen saying "Your device has failed Verification". Ignored it and wait for the reboot.
5. Done
Unroot:
Just flash back stock boot.img
Xposed:
1.Flash the attached Xposed file from twrp.
2.use Material Design Xposed Installer: Download Xposed Installer here
Downgrade to Lollipop:
In case you need to downgrade to Lollipop, follow the instructions with care. Do it at your risk.
Refer to Asus Zentalk Forum and grab the required files from there.
HTML:
fastboot flash token bom-token.bin
fastboot flash ifwi ifwi_ann_a0-mofd_v1-ze551ml.bin
fastboot flash fastboot droidboot.img
fastboot flash splashscreen splashscreen_ze551ml.img
fastboot reboot-bootloader
Now you are back in Lollipop. You can flash back stock recovery(.184 recommended), wipe the device(cache/userdata/system) and then sideload back stock LP or MM as you wish. OR, you can flash custom recovery/boot/system.img start from here.
Good luck!
It worked!Thank you master!I bow now....

It does work, but YMMV, my phone is one of the few that works completely with the beta software. But before running fastboot cmd in adb. Use adb reboot recovery, then fastboot cmd. Phone will reboot twice after sideload of SU.

Assuming that everyone knows how to use adb and its commands
1: Well first make sure adb and drivers are on your pc.
2: Plug phone in make sure USB debugging is on
3: In adb cmd window type "adb devices" to make sure phone is recognized, if so proceed
4: type "adb reboot recovery" phone should boot into recovery with android robot on screen
5: Then type "fastboot boot <twrp.img>" twrp.img is whatever your file is named
6: phone will boot into recovery, go to adb sideload in recovery
7: type "adb sideload <SU.zip>" or whatever you have it named
8: After it's done loading reboot from recovery, it will reboot twice and the screen will say as per OP
9: After phone optimizes...enjoy root.

He's using whats called "tethered TWRP". It's basically running twrp on your phone from your computer instead of actually installing it (which would require unlocking).

To downgrade to Lollipop, is it possible to just use AsusFlashToolInstaller and flash raw firmware? Any harms by doing that?

Guess your ZF2 is not unlocked in LP first, so that you can't see twrp booting. Since you are in Android 6.0 now, try to downgrade to LP, Unlock it, upgrade to 6.0 and then root.

[GUIDE] Root Stock N using jcadduono's Recowvery tool. H830.

Using the following method I was able to successfully ROOT my H830 running stock 20A NOUGAT. With this root method you will get TWRP Recovery and SuperSU. This method WILL wipe your internal storage, so please BACKUP!​
Your warranty is now void. I am not responsible for bricked devices, dead SD cards, or lost photographs.
Please do some research if you have any concerns about root!​
I used jcadduono's method which he describes on the V20 forum [Easy Recowvery ALL CREDITS TO THE AUTHOR. PLEASE GO RATE HIS THREAD AND CLICK THANKS IF THIS WORKS FOR YOU!] https://forum.xda-developers.com/v20/development/h918-recowvery-unlock-v20-root-shell-t3490594​
1. Bootloader Unlock
For this method to work you must have an unlocked bootloader. Despite the fact that I already had an unlocked bootloader, after the upgrade to stock N, jcadduono's script failed to work initially and gave me an error message saying my bootloader was locked. To fix this I had to manually relock and unlock my bootloader one more time. Unlocking/Locking your bootloader will wipe the internal storage of the devices so backup before this step. If you however, already have an unlocked bootloader, feel free to skip this step and go on, although in the end you might have to return to it if you get a "bootloader locked" message in the Recowvery script. If you do skip these steps, don't forget to download the LG Drivers from below.
1. Download and install the latest LG Drivers from HERE
2. Download the minimal adb and fastboot tool from HERE. I recommend the portable version, which you can extract to your desktop.
3. On your phone, go to Developer Options and turn on Enable OEM Unlock.
4. Enter fastboot mode: Turn off your device, press and hold the volume down button, while holding the volume down button connect your phone to your computer by USB, continue holding the volume down button until your device enters into fastboot mode.
5. On your computer go to the folder which you extracted in step 2. Open a command window by holding down SHIFT, right clicking with you mouse inside the folder, and selecting "Open command window here"
6. In the command window type "fastboot oem unlock" to unlock your bootloader, this will erase all of your data.
7. Type "fastboot reboot" to reboot to system.
2. Installing TWRP using Recowvery
Prior to this step I HIGHLY recommend factory resetting your device, if you just unlocked your bootloader, your device was automatically factory reset so you are good to go. Once your phone turns on after a factory reset, I suggest signing into your google account and setting up your phone as if you are going to use it, we will not be factory resetting after this step. However do not download any apps or mess with the settings yet, you can do that later, once your device is successfully rooted.
1. On your computer, download Recowvery from HERE and extract the folder to your desktop.
2. Now on your phone enable USB Debugging in Developer Options.
3. Connect your phone to the computer and make sure File Transfer is chosen in the "Use USB connection for" pop-up.
4. On your computer, download the latest version of TWRP: H830 or H850
5. Rename the downloaded file to "recovery.img" and place it on your phone's internal storage [/storage/emulated/0]
6. On your computer, open the Recowvery folder you extracted in step 1, and click on EasyRecowvery.
7. Once there, type option "5" and "ENTER", in the "Extras and Advanced Tools Menu" disable integrity verification by typing option "7" and "ENTER". Return to the main Menu of Recowvery by typing option "0" and "ENTER"
6. After disabling integrity verification, run the exploit by choosing option "1"
7. Follow the prompts in Recowvery, your phone should reboot about two times in the process.
8. DO NOT Wipe Cache while in TWRP.
8. Once finished, your device should reboot to system and will have TWRP recovery, instead of the stock recovery. The only thing left now is to install SuperSU.
3. Installing SuperSU through TWRP
Although Recowvery does give you an option to install SuperSU through its interface, doing so caused problems in my case. Therefore I recommend manually booting into TWRP and installing SuperSU from there.
1. Download the latest version of SuperSU from HERE and place the .ZIP file on your phone's internal storage.
2. To boot into TWRP, go into the adb and fastboot folder, which I described in the very first steps of this tutorial. There, once again open a command window and type "adb reboot recovery".
3. You should now be in TWRP, there select Install, find the .ZIP file of SuperSU in the file explorer, and install it. DO NOT Wipe Cache after the installation.
4. Reboot to sytem, you should now have a rooted LG G5 with TWRP and SuperSU installed!

I'll try this later tonight, I spent the whole night yesterday trying that. Thanks in advance. ???
Didn't work for me. Thanks for this though. The script actually made it's way through this time (multiple times at this point), but whenever I try to adb reboot recovery I get the "No Command" screen (which I believe is still the stock recovery?). Success all the way through. Don't know what I could be missing.
Also tried manually pushing the recovery image via adb thinking there might be an "Internal Storage" (as seen by pc) vs "/storage/emulated/0" on the phone. No dice either way.

To me it seems like your recovery is not flashing, make sure to download the latest version of TWRP, rename it "recovery.img", and place on the internal storage of the device. If still doesn't work, try a complete clean start. Relock and unlock your bootloader again.
To be safe, I would remove "others try at your own risk" as it will not work and could possibly brick any model other than the H830 and H850. All other models are bootloader locked and I have tested myself; it won't work on anything else.
It worked! Thank you so much.
It worked! Thank you!!!👍👍👍

What do you mean with thiz sentence? We cant unlock our bootloader its not supported, can we still try this method?
Will this trigger some flag or fuse? Or with the flash of the firmware though lgup and locking the bootloader will create a Perfect stock device?
Can someone confirm it works on H850

No, you have to have an unlocked bootloader. I meant if you already unlocked your bootloader, you can skip this step. Possibly it will work once we get bootloader unlocks for other variants of the G5.

The drivers in the post should work for both fastboot and adb. What do you mean, "when in fastboot only waits for device to connect"? You can run the "fastboot devices" command there to see if the device is recognized.
Will not let me run any commands. Just says waiting for device. Crazy, I know.

so this is what i am running into. I know with 100% certainty that the device is oem unlocked. I get the whole, "your device software can not be checked for corruption" screen and everything.
i started the process completely stock, with oem locked. I unlocked it as per your instructions and followed everything closely as far as I can tell. i have tried to re-lock oem . reboot and then unlock it again twice, as well as rebooting pc and G5 multiple times. usb debugging is turned on, and usb options are set to file transfer. still same result.
Any ideas?
EDIT: i will leave the whole post up in case some one makes the same mistakes i did and this helps them out. What i needed to do to fix this was simply set "use usb connection for " to photo transfer instead of file transfer.
Now i am stuck on :\Users\test\Desktop\LgG5 RooT\minimal_adb_fastboot_1.4.1_portable>adb reboot recovery
error: no devices/emulators found like another person before me. hopefully this will be figured out soon
EDIT#2: used adb reboot recovery command with phone turned on and on main screen of launcher, not fast boot, like i was trying at first. and twrp loaded up fine.
dont have a sd card to put superuser.zip on and it seems like i can't reach the internal storage download folder through twrp, or atleast i could not find it, so i ended up sideloading it by going to sideload in twrp and typing "adb sideload SR1-SuperSU-v2.79-SR1-20161221223537.zip"
into it.
i hope that documenting all my mistakes and solutions for everyone to see will help someone running into the same problems i was.

Unable to install TWRP

Hey guys, I'm at a lost here. I don't think I'm that stupid but I am following all steps from the guides to install TWRP without luck. I already managed to unlock my bootloader with Axon7Toolkit. I already certified that QUSB_Bulk driver is installed, I did it with Zadig, but when in EDL mode, even after killing adb, the axon7tool can't find it. I tried installing a zip with the toolkit but when I choose the package, the toolkit simply closes. Is that me? My phone?
Thank you!

What software version are you on?
I was at latest nougat but I downgraded to B10
Doing it via fastboot never fails for me.
Get to fastboot put two img in adb folder (I rename it for ease of typing since I suck) rename to recovery.img
Type this cmd in adb
Fastboot flash recovery recovery.img
Reboot to recovery and root. Done deal
download 3.1.0.0 twrp into your download folder on your desktop enter fastboot into your phone open up your command prmt type fastboot devices, your phone should appear then type fastboot flash recovery then go to the twrp right click drag it into the command prmt air page and place it there. you should see the file then hit enter. It'll take like 5 seconds it's really fast then reboot t recovery. when in twrp it'll ask you to install it again say no and uncheck the to options. DONE.
After loads of stress and bangs on the table I managed to unlock, install TWRP, LOS and root. I removed every driver related to my cell phone, deleted everything I download from it and started from scratch. I installed TWRP via fastboot but wasn't able to enter recovery mode, than I mase the stupidity to lock the bootloader back and got stuck in that password screen. Then I gave another go with the toolkit, unlocked it again and, I don't know how or why, it finally booted TWRP. Now everything is OK. Glad to be back to "Nexus mode" after so many time.
Thank you!

Can't get adb to see my le pro in fastboot

My phone, the LeEco Le Pro 3 LEX727 ZL1_NA US model is on the latest EUI 5.8.021S. I am able to open the adb tools in command prompt and get my computer to recognize my phone with "adb devices", but when I go to the stock fastboot with the Chinese and English writing and use "fastboot devices" nothing shows up. I'm using the latest adb tools and am clueless as to what to do.
Unlock Bootloader - Le Eco Pro 3
If you are not seeing your phone ID in ADB
Did you enable enable Developer options, or chosen MTP?
Its possible that the Android driver driver is outdated, or just try another usb port, preferably in the back of the machine.
Go here to check a whole list of possible causes: https://appuals.com/android-phone-not-showing-up-on-pc/
More than you asked for:
Since you seem to be new to your Leeco phone and new to using custom roms, I am going to go ahead and answer your current question and provide you steps needed to move forward. No big deal, I just copy pasted my notes ( with a few edits)
First steps that you need to take:
1. You will first need to unlock the bootloader :

2. Install Twrp :

****** Scroll down to see: Fastboot Install Method (
3. Right now just use ADB. But for the future, I highly recommend that you buy an OTG drive: it makes the whole process a thousand times easier: They are cheap somewhere near $5 and worth ten times that

You can save your self alot of time by looking up how to give ADB system wide privileges: this will allow you to flash files without tying the directory path.
Mauronofrio created a tool called: "TOOL ALL IN ONE"" it's great, install it and check for updates.
PHP:
https://toolaio.tk
The all is one tool is excellent and you can use it to install everything if wanted.
I usually recommend it for novices that can use it to help with unlocking the bootloader and installing TWRP.
The tool will also update your copy of ADB, android Drivers and provide system wide privileges for ADB
LETS RECAP : Choose using the All in One Tool or the ADB Method
**********BEFORE DOING ANYTHING*******************
Make sure you have enabled the developer tools,
Turned on USB debugging
Authorized your computer on your device I.E: “MTP”
Make sure the All in One Tool can see your device
(*) Select your device from the drop down menu, then click check
(*) Choose to install drivers, and set ADB and fastboot privileges from advanced menu.
(*) First attempt to unlock, then check bootloader status
If you have a X727 you will need to flash : emmc_appsboot.mbn from this zip :
PHP:
https://androidfilehost.com/?fid=313042859668275431
Next, choose Recovery flasher and manually select your copy of TWRP
After you have received the success message, I recommend doing the rest of the install manually within Twrp Recovery.
(*) Reboot into TWRP and begin installation of your Rom, Gapps and Magisk.
Using the ADB Method
Install ADB/Fastboot tools on your computer
PHP:
https://wiki.lineageos.org/adb_fastboot_guide.html
1. Make sure you have enabled the developer tools,
2. Turned on USB debugging, and authorized your computer on your device “MTP”
3. Enter fastboot mode on phone (hold power and VOL -)
4. Make sure adb can see your device when you run "adb devices"
5. type: fastboot devices
6. fastboot flash aboot emmc_appsboot.mbn
7. Run { adb reboot bootloader } - No spaces (before/after)
8. Run { fastboot devices } to make sure you see your device
9. Run { fastboot oem unlock-go } to unlock your device temporarily
10. Run { fastboot oem device-info } to verify unlock status
11. Run { fastboot boot recovery_twrp-3.2.1-0-zl1.img }
12. 5. Reboot back to TWRP and begin installation of your Rom, Gapps and Magisk.
13. 6. If you wiped data, your device will now proceed to re-initialize itself as if from the factory
Concerning your device's storage,
When you boot into twrp you will see a message that states that the storage is encrypted.
*****************Important************************ ******************
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
Ensure that you have TWRP installed as the primary recovery
To remove encryption you will need to format the storage
(Anyone who says otherwise has the X720 and not the X727)
You could also try to skip the formatting step. But you will very likely have permissions issues and get errors and you will eventually have to come back and format ( Again as long as Twrp recovery is install there is very slim chance of ever bricking your phone.
To format the storage
Go to Wipe, choose Format Data and follow the instructions.
This will erase all of photos , music, etc
If you wiped your data partition, you'll need to push the zip file to the newly formatted storage. - This is one BIG reason why using OTG is better. You can use Mauronofrio's "TOOL ALL IN ONE"" for pushing the ROM, Gapps, and Magisk to storage.
Root: You absolutely should root!
NOTE: If you have unlocked the bootloader and flashed TWRP to the recovery partition. But have not yet flashed a Custom Rom the OS will likely reset back to the factory recovery UNLESS YOU ROOT THE SYSTEM. Your device is still unlocked. But the recovery can be overwritten by the stock EUI system, so beware.
Installation of Rom, Gapps, Magisk
Boot into TWRP recovery
1. Go to "Wipe" and then to "Advanced Wipe".
2. Mark "Dalvik / ART Cache", "System", "Data" and "Cache".
3. "Swipe to Wipe" and proceed back the main menu.
4. Go to "Install".
5. Select the ROM zip file and then press "Add more Zips" and select the Gapps zip file, and then the Magisk file.
6. "Swipe to confirm Flash" and wait for some time.
7. After the flashing is finished, just reboot to system.
Finished!
If you need help or have a question message me, I would much rather help you with a successful install versus helping you unbrick your phone.
Thank you for your reply. I figured out the issue. Windows 10 updater wasn't auto installing the driver for some reason even though I have auto update ticked.

You have manually install those drivers usually.
Sent from my LEX720 using xda premium
I have the same issue in Windows 10. All In One Tool sees my x720 in adb mode, but when I switch to bootloader, the phone is gone. Device manager then shows unrecognized android device. I have LTSB version of Windows, so maybe that's why it won't auto install the needed driver. Could anyone point out what kind of driver exactly do I need, so that I can install it manually?

How to update to newest global AA build with root, There is no computer needed. Just restore stock boot img backup from exkm, then go into magisk > uninstall > restore images. Then go to OTA and it will let you install no issues. Then, before rebooting, but after OTA install, go back into magisk, click install, install to inactive slot (after OTA) option. Then reboot. You’ve successfully ota updated and kept root in the process, now remember to take a new boot img backup
